Does anyone have an authoritative record/source that this Deborah who may have married Sylvanus White has the maiden name of Church? I've seen spevculation but no proof. The Mayflower Families book for White does notl ist her as a Church.
The data attached to her on Geni show five husbands. Any proof from a church record or town record?
Frankly, genealogists should not be connecting people to spouses because they are "most likely." There are absolutely no records for a marriage of @Deborah-Church to either Sylvanus White or John Irish. This is in a location where decent original records were kept and are published. It is possible that she married @Sylvanus-White, but unlikely that she married @John-Irish in 1708 (since he married @Priscilla-Southworth in 1708), according to authoritative sources.
Any genealogist worth their salt would denote Deborah without a surname and no connection to any parents.
Undoumented research is genealogy mythology, not worthy of being in a interconnected family tree.
Curators should be applying sound research principles to their work, not guessing at the information. There's enough guessing going on in the family tree data submitted to Geni, Ancestry, FamilySearch and other online trees.
Not that this is a definitive source, but it links Deborah to parents presumably based on the will that mentions the children, but says (fn) that it is unlikely that she was married to John Irish and doesn't mention Sylvanus White.
The Mayflower Families Through Five Generations book (Volume 13) for William White says this about Deborah, wife of Sylvanus White::
"It is suggested she was the dau. of Richard and Elizabeth (Warren) Church, b. Hingham 27 Jan 1656/7.
"Administration on the estate of Sylvanus White of Scituate was granted to his father Peregrine White, Esq. 30 June 1688; Deborah White swore to the inventory of her husband the same day. No further record of Deborah has been found in Plymouth County records."
There is no evidence to support a conclusion that Deborah Church born 1657 is the wife of Sylvanus White. The General Society of Mayflower Descendants has no evidence of the surname or parents of Deborah. That is good enough for me, notwithstanding LDS assertions from church members or assertion by Geni members with absolutely no evidence.
This profile should be disconnected from the parents and siblings.
